Application filed July 12. 1906. Serial No. 325.754

To all whom it may concern:

Be it known that we, WILLIAM F. EDEs, of Lynn, county of Essex,Commonwealth of Massachusetts, and LoUIs P. EDEs', of Cambridge, countyof Middlesex, Commonwealth of Massachusetts, citizens of the UnitedStates, have invented certain new and useful Improvements in AutomaticBall-Cocks, of which the following is a drawings which accompany thesame.

Our invention relatesto automatic ball cocksand is particularly adaptedfor use in controlling the flow of water into the flushing tanks ofwater closets.-

' The object of-our invention is to produce a ball cock wherein thepressure of water upon "the ball valve will tend to close it.

Another object of our invention is to so arrange the ball valve and seatand the the ball valve that a small movement of said operating devicewill quickly raise the ball valve to its full height, and will close itagain as quickly.

In the drawings accompanying this specificationFigure l'is a sectionalside elevation of our improved ball cock. Fig. 2 is a sectionalelevation throu h line 22, Fig. 1. Fig. 3 is a sectional elevation ofthe wherein the water is caused to flow into the same through the side.v

The body of the ball cock is represented by the numeral 1 and isprovided with-the screw threaded portion 2 for attaching it to the tankor whatever apparatus with which it may be used; 3 is a screw threadedcap hollowed as indicatedat 5, secured in the top of the part 1. y

4 is a water passage through which the water flows upward as indicatedby the arrow upon the top of the ball-cock; 6 is the water passageleading to-the valve opening 7 8 is'the ball valve designed to closetheflowing through the passage 6 and the valve 7.

10 is the ball valve operating device which has a bearing in the side ofthe body part 1 and is provided with the small porabuts against theinside ofthe stufling' box 13, the box 13 being screw threaded as at .li-upon the outer. surface of the bearin 15 is a stem having attached toit a collar 16 serrated upon its outer face 17 is a cdllar which fitsupon the outer end of the stem 15 and has serrated faces to contact withthe serrations on the collar 16; 18 is a thumb nut threaded upon theouter end of the stem 15 and is adapted to keep the collar17 in contactwith the collar 16, the serrations being provided to prevent saidcollars 16 and 17 slipping upon each other, and to provide for adjustingthe stem 19 up or down as is found necessary; the stem 19 being designedto receive a ball-float which will float upon the surface of the" waterin a flushing-tank, and as it rises or falls, open the ball-valve8through a shoulder on the collar 20.

The collar 20 is provided with the circular recess 21 shaped to fit thesurface of the ball 8, the surface of the recess 21 being adjustedslightly away from the surface of the ball 8 so that said ball-valve 8will seat upon the seat 7 when closed. When opened, the corner 22 of theball and quic ly raise it to its full height by slightly revolving thestem 15. This insures the quick openin and closing of the valve.

In the modifie form shownin Fig. 3 the portion 20 will contact with thestem and operating device is identically the same as that shown in Figs.1 and 2. An inlet direct y into the down-flow passage 6-. Said sideinlet is provided with the projecting portion 23 screw-threaded at 24and tapering on the inner edge at 25 to receive the union coupling andnut. The lower end of the outlet 9%; is provided with screw threads withwhich to attach it to standard size piping.

Having described our invention, what we claim is 1. An automaticball-cock having an inlet and outlet passage, the inlet passage leadingto the top of a ball-valve; a ball-valve; a

passage 4% is provided, which leads valve opening device consisting of arotatable stem provided with a circular disk mounted thereon; a concavedrecess in said' disk, said recess being formed and arranged so that theangle of theends of said recess with the periphery of the disk willcontact with, and quickly raise and lower the ballvalve.

2. The combination in an automatic .ballvalve of a' body part having aninlet and outlet passage, the inlet passage leading to the top of theball-valve; a ball-valve; a seat for same; a ball-lifting devicecomprising a rotatable stem having a circulardisk provided with acon'caved reeess therein, said concaved 'l recess being formed andarranged so that the angle formed by the ends of the recess and,eriphery 0f the disk'wili uickly lift the all-valve a predetermined tionf said disk; and'an adjustable float on the stem for controlling theflow of Water. In witnesswhereof. We have hereunto set distance and asquicklypermit the same to closev upon rota- WILLIAM F. EDES. LOms P.EDES.
